The advanced photocatalytic performance of V doped CuWO4 for water splitting to produce hydrogen

Photo-Fenton Process over an Fe-Free 3%-CuO/Sr0.76Ce0.16WO4 Photocatalyst under Simulated Sunlight

“…The specific type of Cu species cannot be identified by the SEM analysis. However, the chemical valence of the Cu element is +2, which was determined by the characteristic peaks of Cu 2p 1/2 and 2p 3/2 at 955.0 and 935.0 eV, respectively (see Figure b). ,, Hence, the Cu species is CuO. Figure c–e shows no change in the high-resolution Sr 3d, Ce 3d, and W 4f between the 3%-CuO/Sr 0.76 Ce 0.16 WO 4 and Sr 0.76 Ce 0.16 WO 4 samples.…”

Copper tungstate assisted photocatalytic degradation of Industrial (dye and pharmaceutical) products in water

“…Figure 1b represents the optical bandgap energies of 2.90 eV, which is obtained using the Tauc plot for CuWO 4 . The obtained value of the bandgap, has coherence compared to other investigations that consider CuWO 4 as a photocatalyst of interest with a bandgap of 2.25 eV to 2.4 eV [44][45][46]. Hence, CuWO 4 has a narrow bandgap because of this small bandgap energy, it can resist photocorrosion [47,48] in an aqueous solution at a neutral pH.…”

P-incorporated CuO/Cu2S heteronanorods as efficient electrocatalysts for the glucose oxidation reaction toward highly sensitive and selective glucose sensing

“…S5b, ESI †). These phenomena are evidence for the successful integration of P to CuO/Cu 2 S. Because the ionic radius of P ions (0.044 nm) is smaller than those of the O ions (0.135 nm) and S ions (0.184 nm), 28 the partial replacement of O and S with P leads to a lattice shrinkage and thereby causing a shift in the direction of higher angles of CuO and Cu 2 S diffraction peaks, 34 which is in accordance with the HR-TEM observations. According to the XRD results, the crystal structures of CuO and Cu 2 S are determined and illustrated in Fig.…”
